10/// # Loosely coupled layers, that together define shapes
11///
12/// Shapes are not a monolithic thing in Fornjot, but instead are defined by
13/// several, loosely coupled layers. These layers are owned by this struct.
14///
15/// ## Implementation Note
16///
17/// It is totally conceivable that one day, this system of layers is extensible
18/// and more layers can be defined by third-party code. The foundation for that,
19/// the loose coupling and inter-layer communication via events, is already
20/// there, conceptually.
21///
22/// For now, there is no need for this, and all layers are just hardcoded here.
23/// That can be changed, once necessary.
